BRAKE-EIGGING.

Specification of Letters Patent.

Iatented July 23, 1915.

Application filecl April 17, 1915. Serial No.'22,131.

To all whom it may concern:

Be it known that I, CLEMENT F. Moonn, a citizen of the United States, residing at Chica o, in the county of and useful Improvements in Brake-Rigging, of which the following is a specification.

This invention relates to railway brakes, and its object is to provide a simple and cheap brake rigging so arranged and located that there is no danger of the parts, if they should be broken, falling on the track rails.

The herein stated ob ect is attained by means of a novel combination and arrangement of parts to be hereinafter described and claimed, reference being had to the acwhich- Figure 1 is an elevation of a. car truck showing the application of the invention;

Fig. 2 is a horizontal section on the line 22 of Fig. 1; Fig. 3 is an enlarged elevation of oneof the brakes, and Fig. 4 is a perspective detail Referring specifically to the drawings, the invention is shown applied to an ordinary car truck having columns 5, an arch bar 7, aninverted arch bar 8, and a pedestal tie bar 9. The spring plank 10 supports the bolster springs 11 in the usual'manner. The wheels are shown at.12 and the journal boxes. at 13. These parts are all arranged in theordinary manner and as they form no part of the present invention, a further description is deemed unnecessary.

Mounted on the truck, at the bottom of the columns 5, are brackets 14 suitably shaped to clear the inverted arch bar 8 and the pedestal tie bar 9, said brackets being apertured to receive the lower ends of the column bolts '15, and being secured by nuts '16 screwed on said bolts. -'In line with the brackets 14, the front and rear edges 'of the spring planks 10 carrybrackets 17. The brackets '14 and 17 have versely of the truck and having crank bends 19 intermediate theirv ends. These rock shafts carry brake heads 20 provided with the usual detachable brake shoes 21, the brake heads having rear slots 22 through which the crank portions of the rock shafts pass. The brake heads and-their supports are so positioned on the truck that the brake shoes are opposite the tread of the respective wheels 12, a each wheel,

Cook and State of Illinois, have invented certain new .bolts 15,

through their arms bearings which. support rock shafts 18 extending trans-- brake being provided for On one end of each rock shaft 18 is made fast an arm 23, which, when it is swung,

" rocks the shaft to apply or release the brakes.

Pivotally mounted on top of the arch bar 7, by the upper end of one of the column lever 24, said lever swinging horizontally. The other column bolt secures a bracket to which is pivoted, intermediate its ends, at 26, a vertically swinging lever 27. The lower end of the lever27 is connected by a rod 28 to the upper end of one of the arms 23, the other one of said arms being connected by a rod 29 directly to the lever24'. The upper end of the lever 27 isconnected by rod 30 to the same end of the lever 24 to which the rod 29 is connected.

By thearrangement of levers and rods hereinbefore described, the rock shafts 18, 23, are simultaneously operated to actuatethe brakes when the lever 24 is swung. The rods 28 and 29 will be provided with turnbuckles, as shown in Fig. 4,so that they may be lengthened or shortened.

The brake mechanism hereinbefore described is the same on both sides of the truck, and the levers 24 of the two sets of brakes are connected at their inner ends to an equalizer bar 31 by links 32. The equalizer bar has a suitable connection 33 with the piston of the brake cylinder, I The equalizer bar is supported on hangers 34- mounted on the'car frame, and similar under the head of the latter, is a' or the cylinder rod.

hangers 35 are provided for the lever 24.

If any of the parts break, they are held up by the hangers and thus prevented from falling on the roadbed or the rails. 'The thereof. These auxiliary supports serve to steady the brake heads on their short upward and outward movement to apply the brake shoes. The brake heads are prevented from dropping off the cranks 19 by pins 41 passing through the brake heads back of the cranks. r

The brake rigging hereinbeforedescribed has been devise to obviate the danger of by loops 37 which pass BEST AVAILABLE COPY Wrecks or derailments from the parts drops ping'on the rails of the track. The usual brake beam extending transversely of thetrack has .been eliminated, and the parts have been so positioned that in the event of breakage they will not drop on the rails, the parts not supportedby-the hangers 34 and 35 being on the outside of the rails and readily accessible for repairs without going under the car or between the rails.

I claim I l. The combination with a railway car truck; of brackets carried by the truck, rock shafts supported by the brackets and having cranks, brake heads carried by the cranks, .arms fixed onthe rock shafts, a horizontally swinging lever carried by the truck, operatlve connections between the lever and the respective arms of the rock having cranks,

shafts,

'2. The combination with a railway car truck of brackets carried by the truck, rock shafts supported by the brackets and cranks, arms fixed on the rock shafts,a hori- --zontally swinging lever carried by the truck,

an operative connection between the lever and the arm of one of the rock shafts, a vertically swinging lever carried by the truck, a connection between. the arm of the other rock shaft and one end of the lasttioned lever, and

' having cranks,

mentioned lever, a connection between the other end of said lever and the first-menactuating means for the first-mentioned lever.

3. The combination with a railway car truck, of brackets carried by the truck, rock shafts supported by the brackets and brake heads carried by the cranks, arms fixed on the rock shafts, a horizontally swinging lever carried by the truck, operative connections between the lever and the respective arms of the rock truck; of brackets and actuating means for the lever.

brake heads -carried by the 1 plank, brackets mounted on the bottom of the columns by the column bolts, rock shafts supported by the brackets and having cranks, brake heads carried by the cranks,i

arms fixed on the rockshafts, a horizontally swinging lever carriedby the truck.

' operative connections between the lever and the rock shafts and the respective arms of actuating means for the lever.

'6. The combination with a railway car truck; of brackets carried ,by the truck, rock shafts supported by the brackets and having cranks, brake heads carried by the cranks, arms fixed on the rock shafts, a horizontally swinging lever carried by the'truck, operative connections between the lever and the respective arms of the rock shafts,'.actu- .ating means for. the lever, and auxiliary actuating means for the lever, and

' truck, operative connections between the lecarried by the spring.

supports carried by the spring plank and" loosely connected to the brake heads.

In testimony whereof I aiiix my signature in presence of two witnesses.
